Notice: This website is continuously updated as new conference proceedings and journal volumes are published. Consequently, the figures presented here may differ from those reported in our publications.


A brief overview of our methodology is provided on the Methods page, along with references to publications documenting our approach and links to the code and data used in each study.


The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates.

Pseudocode Yes Algorithm 1: Policy-Adaptive Estimator Selection via Importance Fitting (PAS-IF)
Open Source Code Yes Our experiment code is available at https://github.com/sony/ds-research-code/tree/master/aaai23-pasif
Open Datasets Yes Note that our synthetic experiment is implemented on top of Open Bandit Pipeline (Saito et al. 2021a).7 https://github.com/st-tech/zr-obp
Dataset Splits No The paper describes data collection and subsampling for pseudo datasets but does not provide specific train/validation/test dataset splits (e.g., percentages or counts) for their main experiments.
Hardware Specification No The paper does not provide any specific hardware details such as CPU or GPU models, processor types, or memory used for running the experiments.
Software Dependencies No The paper mentions using "Open Bandit Pipeline" and "SLOPE" but does not provide specific version numbers for these or any other software dependencies.
Experiment Setup Yes For PAS-IF, we set S = {0, 1, . . . , 9}, k = 0.2, η = 0.001, and T = 5, 000, and select the regularization coefficient λ from {10 1, 100, 101, 102, 103} by a procedure described in Section 4.
